No, it's dormant this time of year, plus where I live the ground is pretty much sodden throughout the winter. Trying to mow it would just make a huge mess. If you miss the last mowable day you just have to leave the lawn a bit shaggy until April. Had to train the pet Aussie to LEAVE IT ALONE. (It's still unnatural to him though, and he still calls winter dormant deciduous trees "browned off.")
